Analysis parameters

In the Setup page, press Analysis softkey (if one parameter is selected in the current

screen, press Top Menu soft key to display the right menu keys and click on Analysis).

Those parameters are only linked to the current active fiber.

used for the acquisition.

and entails the loss of the measurement statistics.

the threshold is determined automatically.

the threshold can be set from -79.9 to +30 dBm

The grid serves as a detection reference: it must therefore be

Regular, Manual, ITU DWDM, ITU CWDM, LR4/ER4-100G,

LR4/ER4-40G or 10x10-100G. The choice of grid takes priority

over the choice Channel Selection. For example, it is not

possible to choose Channel selection = Grid, if the option

selected for the grid is «Without» or «Conventional».
